How do I do a touch screen calibration on this copier?

I think you'll have to run a factory reset.

However, I cannot find any way of carrying this out. You'll need to contact Ricoh or their dealers, I'm afraid.

The touch screen could have lost its calibration, but there is a good chance that it is bad, and needs to be replaced. To calibrate it, push the yellow clear modes key, then the numbers 1, 9, 9, 3, then push the red "Clear / Stop" key 5 times, and choose number one. Follow the prompts. Use a stylus or other dull pointed item. If you don't get a response, you need a new touch screen.

Which model of Ricoh are we talking about here? If touch screen is not responding before replacement, re-calibrate touch screen or replace it. I can help you with the calibration code if you require. If the touch screen is not responding after replacement, check whether the replacement lcd display panel was installed reverse as the connectors will not have contact.

Press the keys listed below, please note you need to press the Clear/Stop key 5 times. The screen will change after entering the keys and touch screen calibration will be option number 1. The calibration will consist of pressing a couple of small circles on the screen.

Clear Modes->1-9-9-3->Clear/Stop(5 times)
or
Reset->1-9-9-3->Stop(5 times)

Perhaps your touch screen need calibration? Try calibrate your touch screen. (08-692)
